(Prime Numbers) An integer is said to be prime if it's divisible by only 1 and itself. For ex_
ample, 2. 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not.
a) Wright a function that determines whether a number is prime.
b) Use this function in a
c)Initially, you might think that is the upper limit for which you must test to sec whether a number is prime. but you need only go as high as the square root of n. Why? Rewrite the program. and run it both ways. Estimate the performance improvement.

- % WRITE CODE BELOW: % Step 1: Write a function called "collatz" below where you take an input % n, and if n is odd, return 3*n+1. If n is even, return n/2. (You need to % compute mod (n, 2) to test for even/odd. If mod(n,2)==1, n is odd, % otherwise n is even) Matlab codearrow_forwardComputer Science This is an introductory exercise to the manipulation of random variables with Python as a language for scientific computing and numerical computation.

You have to take a positive number from input and show all the Fibonacci numbers belongs to that range. If the number is not valid then notify the user and ask to input positive number again. If valid, then print the series. Input: Key in a number: 10 Output: Fibonacci Series: 0 1 1 2 3 5 8 13 21 34 Do you want to continue (y/n)? n Good bye!!

Odd-Even-inator by CodeChum Admin My friends are geeking out with this new device I invented. It checks if a number is even or odd! ? Do you want to try it out? Instructions: In the code editor, you are provided with a function that checks whether a number is even or odd. Your task is to ask the user for the number of integer, n, they want to input and then the actual n number values. For each of the number, check whether it is even or odd using the function provided for you. Make sure to print the correct, required message. Input 1. Integer n 2. N integer valuesarrow_forwardComputer-Assisted Instruction) The use of computers in education is referred to as computer- assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.arrow_forwardA(n) statement is a statement that returns a value to the statement that called the function.
